I bought a Luminous RO Water Purifier (Touch plus) just a year ago and what impresses me more than the product is the service from the company. During the first year they regularly came home to check the candle and clean up the equipment.
Recently when I had a leakage, I called their customer service (I presume in Delhi) and they just took my name and said the help will be there with in 24 hours. I was very skeptical but was given a pleasant surprise.
To my surprise the service person was in my home with in 2 hours and the entire work was completed within 3 hours. In fact I even had a call the next day to make sure that my problem is resolved and I appreciate this type of service mentality shown in our country which often is criticized for lack of service.
